> This is an optional API that will be implemented by the renderers. It
> allows to fetch the current contents of a surface, essentially the buffer
> contents from a client buffer, converted to an RGBA format.
> 
> This is meant as a debugging API. The implementations may be heavy and
> cause a stall, so they are not intended to be used often during normal
> operations.
> 
> Renderers are expected to convert whatever data a surface has to a single
> RGBA format.
